D - BUG: undefined references, DMD

reply Russ Lewis <spamhole-2001-07-16 deming-os.org> writes:
I ran across this on RH 7.2, gcc 2.96 (same as you Walter)

I get "undefined reference" errors when I compile the following code:



int main(char[][] argv)
{
  switch(argv[0])
  {
  case "asdf":
  case "jkl":
    return 1;

  case "qwerty":
    return 2;

  default:
    return 0;
  }
}



I compiled it with:
    dmd -c dmd_bug2
    cc -lphobos -lpthread dmd_bug2.o -o dmd_bug2

What is the undefined reference to?

_d_switch_string and _d_array_bounds.

I originally came across this error when I tried to link my large app
(ported from DLI) and got to the linking phase.  In that larger app, I
have lots (100 or more) of such errors, many of which seem to be link
problems to phobos.  Some other ones seem to be internally implemented
functions, like _aaIn _aaGet _init_TypeInfo_Aa and such.

I'm confused, too.  I can find the symbols with grep.  I do get "bad

On RH7.2, gcc 2.96, I get these errors:



dmd_bug2.o: In function '_Dmain':
dmd_bug2.o(.gnu.linkonce.t_dmain+0x30): undefined reference to

On RH9, gcc 3.2.2, I also get this error (first, before the others):



/usr/bin/ld:
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../libphobos.a(gc.o): bad
relocation section name '.rel.gnu.linkonce.t_d_new? '




BTW, /etc/dmd.conf doesn't seem to work for me so far...so I'm having to add
-I<phobosPath> to my dmd commands.

I've tried to build a new libphobos.a from the sources, t osee if that would

* FIXED: the makefile mentions "deh2.d", which doesn't exist, so I deleted it
* FIXED: the makefile has the wrong location for DMD, so I changed that to just
"dmd"
* COULDN'T FIX: outbuffer.d calls vsnprintf, which doesn't seem to be defined in
any source file I can find

I'm really appreciating your continued hard work, Walter.

 I've tried to build a new libphobos.a from the sources, t osee if that

 clear up the problem.  I ran into a couple of problems.

 * FIXED: the makefile mentions "deh2.d", which doesn't exist, so I deleted

All right, but it never tries to add it to libphobos.a!
 * FIXED: the makefile has the wrong location for DMD, so I changed that to

 "dmd"

Ok.
 * COULDN'T FIX: outbuffer.d calls vsnprintf, which doesn't seem to be

 any source file I can find

vnsprintf is part of the C runtime library. It should be in c.stdio.d
 I'm really appreciating your continued hard work, Walter.

Thanks!

Ok, I've been stepping through this thing, trying to link something together.
Walter, is this src/phobos the directory you built libphobos.a from?  I'm having
a heck of a time trying to get things to work.

Right now, I'm stuck on deh.c, line 528.  I'm getting a few errors.  First of
all, gcc seems to gripe about that __stdcall modifier; I tried commenting it out
and got a little further, but I don't know if we need to leave it in.

Then, on line 535, I get "'_EBP' undeclared"

Any fixes for these?

Thanks again,
    Russ
